What's in Park City's water
PFAS (forever chemicals)
1.7×above guideline
Detected above the EPA's 4 ppt limit for PFOA/PFOS — the "forever chemicals" linked to cancer and immune effects. Compounds found: PFBS, PFHxA, PFOA, PFOS, PFPeA.
Nitrate
Violation on record
4 EPA violations on record (most recent 2025). Nitrate enters water mainly from fertilizer runoff, septic systems, and animal waste. High levels can interfere with the blood's ability to carry oxygen, a special danger for infants. Long-term low-level exposure has also been linked to elevated cancer risk in some studies.
Arsenic
Violation on record
2 EPA violations on record (most recent 2022). Arsenic is a naturally occurring element that dissolves into groundwater from rock and is also released by mining and industry. Long-term exposure is associated with several cancers and with skin, cardiovascular, and developmental harm. It is common in parts of the Southwest.
Uranium
Violation on record
1 EPA violation on record (most recent 2024). Uranium occurs naturally in rock and dissolves into groundwater, with extra contributions from mining in some regions. It is both a radioactive and a toxic metal; long-term exposure mainly damages the kidneys and increases cancer risk. It is widespread in Western groundwater.
Radium (combined -226 & -228)
Violation on record
1 EPA violation on record (most recent 2024). Radium is a naturally radioactive element that leaches from rock into groundwater. Long-term exposure increases the risk of bone cancer and other cancers because it concentrates in bone. The federal limit covers the combined activity of radium-226 and radium-228.
Gross Beta / Photon Emitters
Violation on record
1 EPA violation on record (most recent 2024). Beta and photon emitters are radioactive contaminants that can come from natural deposits or from nuclear activity. Long-term exposure increases cancer risk. The federal limit is expressed as an annual dose rather than a simple concentration.
Water hardness
very hard
Park City's water is very hard. Hardness isn't a health risk, but it drives scale on fixtures and water heaters, shortens appliance life, and leaves skin and hair dry.
